基于峰值采样圆感应同步器测角系统研究
|
摘要
在高精度伺服系统中,以绝对式圆感应同步器作为测角元件,解码电路通常都会使用轴角转换芯片,将感应同步器输出的模拟信号转换为角度数字量,但轴角转换芯片价格昂贵并且都需要外围大量的电阻电容进行配置才能满足其转换精度以及跟踪性能,非常不便且缺少灵活性。研究一种对感应同步器输出的正余弦信号进行峰值采样,从而通过DSP计算得出角度值的测角系统。此系统不仅与传统的轴角转换系统一样可以满足高精度测角需求,而且摒弃了大量的外围配置电路,将角度转换处理数字化,具有更好的灵活性及扩展性。
In the high accuracy servo system,people always use the shaft position digitizer to transfer the rotaryinductosyn′s signal,it is very inconvenient,because the shaft position digitizer is expensive and will need so much large additional resistances and capacities to set it.The paper researches a system that can use the DSP to calculate the angle value when the peak value of the rotary-inductosyn′s sine and cosine signal has been sampled.This system doesn′t need additional circuit and can acquire the high accuracy like the shaft position digitizer,it makes the shaft position converter digital and can been extend conveniently.
